Abstract
The invention discloses cooperative treatment of emulsification waste liquid sludge and waste and old circuit board nonmetallic powder. The treatment comprises the following steps: drying the emulsification waste sludge to obtain a first ingredient; sieving the waste and old circuit board nonmetallic powder to remove part of the long fiber to obtain a second ingredients; mixing the first and second ingredients according to a certain proportion to obtain a mixture; and pressing the mixture to obtain a derived fuel. The cooperative treatment of two wastes with high pollution and difficult to separate molding can produce derived fuel of resource utilization type, so as to achieve the purpose of hazardous waste disposal as well as recycle heat energy; due to the complementary characteristics of the emulsification waste liquid sludge and waste and old circuit board nonmetallic powder, binder and heating are not required for the molding of derived fuel, and the molding can be realized only by pressure. Therefore, the treatment method has low energy consumption and high environmental protection benefit. The invention also provides the application of the emulsification waste liquid sludge and waste and old circuit board.
Description
Technical field
The present invention relates to waste reclamation field, relate in particular to associated treatment and the application at a kind of emulsified waste liquid mud and nonmetallic metal powder of scrap circuit boards end.
Background technology
Emulsified waste liquid mainly comprises mixture, emulsion (cream), cooling agent, lubricant, hot candied agent of useless soap lye, oil emulsion, hydrocarbon and water etc., belongs to hazardous waste.When Separation of Solid and Liquid is carried out in emulsified waste liquid press filtration after breakdown of emulsion, flocculation, anaerobic and aerobic reaction, liquid can qualified discharge through further processing, and mud still belongs to danger useless needs to be processed.Because emulsified waste liquid relatively disperses, the harm of a small amount of discharge does not highlight, and adds that laws and regulations are not very perfect, and people's environmental protection ideas is indifferent and be reluctant to bear the factor such as dispose waste liquid, and causes a large amount of emulsified waste liquids to be discharged into the lower water of life.Although emulsified waste liquid treatment station has been set up in the area that some mechanical industries are assembled, but because sludge quantity is few, directly carry out landfill, what have does not even just sneak into rubbish through any processing and enters landfill yard, so not only cause the long-term pollution to soil, underground water source, and be a kind of wasting of resources.
The recovery of old circuit board adopts the technique separating metal of fragmentation, sorting and nonmetal conventionally.Metal can be recycled, but the nonmetal filler usually used as waterproof roll, composite is used, but consumption is limited, and a large amount of goes out of use, and in some areas, has caused severe contamination, is also a kind of waste of energy.
Summary of the invention
In order to solve the technical problem existing in background technology, the present invention proposes associated treatment and the application at emulsified waste liquid mud and nonmetallic metal powder of scrap circuit boards end, emulsified waste liquid mud and the pollution of old circuit board to environment have not only been reduced, also it is carried out to energy recycling, accomplished that innoxious, the resource of discarded object and minimizing dispose.
On the one hand, the present invention proposes the associated treatment at a kind of emulsified waste liquid mud and nonmetallic metal powder of scrap circuit boards end, comprise the following steps:
Step 1, described emulsified waste liquid mud is dried, obtain the first batching;
Step 2, the screening of dry nonmetallic metal powder of scrap circuit boards end is removed to part long fibre obtain the second batching;
Step 3, described the first batching and the second batching are mixed by a certain percentage, obtain compound;
Step 4, described compound is pressed, obtains derivatived fuel.
Further, described non-metal powder obtains by the old circuit board fragmentation being dried and after sub-electing metal.
Further, the temperature of described oven dry is 80 ℃-120 ℃.
Further, the preferred temperature of described oven dry is 90 ℃-100 ℃, and the time of oven dry is 2-4 hour, and in drying course, constantly stirs described emulsified waste liquid mud.
Further, described first batching water content be less than 20% and described emulsion sludge also there is mobility.
Further, described the second batching after screening is carried out to drying and processing, the batching of second after oven dry moisture is less than 5%.
Further, in step 3, described the first batching and the second batching are delivered in double-screw mixer and are mixed with auger conveyor.
Further, the preferred 3:7 of mass ratio that described the first batching is mixed with the second batching.
Further, in step 4, pack described compound into mould, be pressed into bulk or strip derivatived fuel.
The associated treatment at emulsified waste liquid mud provided by the invention and nonmetallic metal powder of scrap circuit boards end, emulsified waste liquid mud and these two kinds of contaminatives of old circuit board discarded object high and that be difficult to independent moulding and utilization are carried out to cooperative disposal, finally make can recycling derivatived fuel, both reach the object of disposing danger wastes, can recycle heat energy again; Due to the two complementary characteristic of emulsified waste liquid mud and old circuit board, while making moulding derivatived fuel, do not need to add any binding agent, also do not need heating, only depended on pressure can be realized moulding, so this processing method energy consumption is low, processing cost is low, environmental benefit is high.
On the other hand, the invention provides the application at a kind of emulsified waste liquid mud and nonmetallic metal powder of scrap circuit boards end, the derivatived fuel that above-mentioned various cooperative processing methods are obtained is as the auxiliary fuel of cement burning.
Using the derivatived fuel obtaining directly as the auxiliary fuel of cement burning, reclaim the energy consumption of the heat energy reduction cement burning in two kinds of discarded objects, importantly utilize the calcining of cement to absorb the heavy metal element in two kinds of refuses, reduce to pollute and lime-ash discharge, realize innoxious, resource, minimizing disposal.
